Product Description:

Solid phase extraction (SPE) is a physical extraction process that includes liquid and solid phases. In the extraction process, the adsorption force of the solid to the analyte is greater than the sample mother liquid. When the sample passes through the SPE column, the analyte is adsorbed on the solid surface, and other components pass through the column with the sample mother liquid, and then the analyte is removed with an appropriate solvent Eluted down. SPE has a wide range of applications, such as the analysis of biological fluids including blood, urine, serum, plasma and cytoplasm; the analysis of milk processing, wine, beverages and juices; the analysis and monitoring of water resources; fruits, vegetables, grains, and various plant tissues.
